Hi, I'm hitting a bug when git-push-ing to a Linux PPC machine. In general, pushing works well, but pushing some particular commits breaks reproducibly with : fatal: early EOF error: unpack failed: unpack-objects abnormal exit To ssh://localhost//home/perms/moy/prive/dest ! [remote rejected] master -> master (n/a (unpacker error)) I've put the guilty files on my website and wrote a reproduction script: #!/bin/sh rm -fr source dest git init source git init --bare dest dest=$PWD/dest cd source echo foo > bar.txt git add . git commit -m init git push ssh://localhost/$dest master wget 'http://www-verimag.imag.fr/~moy/tmp/git-bug/Conception Manual.docx' wget 'http://www-verimag.imag.fr/~moy/tmp/git-bug/Extreme Programming.doc' git add . git commit -m "bug" git push ssh://localhost/$dest master The full output is attached (the error message for the last push is given above). The machine on which I get this (let's call it "A") says : $ ssh -Version OpenSSH_4.3p2, OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008 $ uname -a Linux A 2.6.18-128.7.1.el5 #1 SMP Wed Aug 19 04:08:13 EDT 2009 ppc64 ppc64 ppc64 GNU/Linux $ cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.4 (Tikanga) (it's a 32-bit distribution although the machine is 64bits) $ git --version git version 1.6.5.2 (compiled myself, "make test" passes) According to my experiments, the problem is on the receiver side. If I do the same as above, with source/ and dest/ directories on two different machines, then if source/ in on A and dest/ anywhere else, it works, and if dest/ is on machine A, I get the same error. If I push using "file://" instead of "ssh://", then everything works well. If instead of push-ing, I go to dest/ and do a fetch, then it works well too. Does anyone have any idea on what's going on? If anyone has a machine similar to mine (ppc64), can he/she run my reproduction script and tell me if the bug happens? Thanks a lot,
